NAME
kdc.conf - Kerberos V5 KDC configuration file
The kdc.conf file supplements krb5.conf(5) for programs which are typically only used on a
KDC, such as the krb5kdc(8) and kadmind(8) daemons and the kdb5_util(8) program.
Relations documented here may also be specified in krb5.conf; for the KDC programs
mentioned, krb5.conf and kdc.conf will be merged into a single configuration profile.
Normally, the kdc.conf file is found in the KDC state directory, /etc/krb5kdc. You can
override the default location by setting the environment variable KRB5_KDC_PROFILE.
Please note that you need to restart the KDC daemon for any configuration changes to take
effect.
STRUCTURE
The kdc.conf file is set up in the same format as the krb5.conf(5) file.

[kdcdefaults]
With one exception, relations in the [kdcdefaults] section specify default values for
realm variables, to be used if the [realms] subsection does not contain a relation for the
tag. See the [realms] section for the definitions of these relations.
• host_based_services
• kdc_ports
• kdc_tcp_ports
• no_host_referral
• restrict_anonymous_to_tgt
kdc_max_dgram_reply_size
Specifies the maximum packet size that can be sent over UDP. The default value is
4096 bytes.
[realms]
Each tag in the [realms] section is the name of a Kerberos realm. The value of the tag is
a subsection where the relations define KDC parameters for that particular realm. The
following example shows how to define one parameter for the ATHENA.MIT.EDU realm:
[realms]
ATHENA.MIT.EDU = {
max_renewable_life = 7d 0h 0m 0s
}
The following tags may be specified in a [realms] subsection:
acl_file
(String.) Location of the access control list file that kadmind(8) uses to
determine which principals are allowed which permissions on the Kerberos database.
The default value is /etc/krb5kdc/kadm5.acl. For more information on Kerberos ACL
file see kadm5.acl(5).
database_module
(String.) This relation indicates the name of the configuration section under
[dbmodules] for database-specific parameters used by the loadable database library.
The default value is the realm name. If this configuration section does not exist,
default values will be used for all database parameters.
database_name
(String, deprecated.) This relation specifies the location of the Kerberos
database for this realm, if the DB2 module is being used and the [dbmodules]
configuration section does not specify a database name. The default value is
/etc/krb5kdc/principal.
default_principal_expiration
(abstime string.) Specifies the default expiration date of principals created in
this realm. The default value is 0, which means no expiration date.
default_principal_flags
(Flag string.) Specifies the default attributes of principals created in this
realm. The format for this string is a comma-separated list of flags, with '+'
before each flag that should be enabled and '-' before each flag that should be
disabled. The postdateable, forwardable, tgt-based, renewable, proxiable,
dup-skey, allow-tickets, and service flags default to enabled.
There are a number of possible flags:
allow-tickets
Enabling this flag means that the KDC will issue tickets for this principal.
Disabling this flag essentially deactivates the principal within this realm.
dup-skey
Enabling this flag allows the principal to obtain a session key for another
user, permitting user-to-user authentication for this principal.
forwardable
Enabling this flag allows the principal to obtain forwardable tickets.
hwauth If this flag is enabled, then the principal is required to preauthenticate
using a hardware device before receiving any tickets.
no-auth-data-required
Enabling this flag prevents PAC or AD-SIGNEDPATH data from being added to
service tickets for the principal.
ok-as-delegate
If this flag is enabled, it hints the client that credentials can and should
be delegated when authenticating to the service.
ok-to-auth-as-delegate
Enabling this flag allows the principal to use S4USelf tickets.
postdateable
Enabling this flag allows the principal to obtain postdateable tickets.
preauth
If this flag is enabled on a client principal, then that principal is
required to preauthenticate to the KDC before receiving any tickets. On a
service principal, enabling this flag means that service tickets for this
principal will only be issued to clients with a TGT that has the
preauthenticated bit set.
proxiable
Enabling this flag allows the principal to obtain proxy tickets.
pwchange
Enabling this flag forces a password change for this principal.
pwservice
If this flag is enabled, it marks this principal as a password change
service. This should only be used in special cases, for example, if a
user's password has expired, then the user has to get tickets for that
principal without going through the normal password authentication in order
to be able to change the password.
renewable
Enabling this flag allows the principal to obtain renewable tickets.
service
Enabling this flag allows the the KDC to issue service tickets for this
principal.
tgt-based
Enabling this flag allows a principal to obtain tickets based on a
ticket-granting-ticket, rather than repeating the authentication process
that was used to obtain the TGT.
dict_file
(String.) Location of the dictionary file containing strings that are not allowed
as passwords. The file should contain one string per line, with no additional
whitespace. If none is specified or if there is no policy assigned to the
principal, no dictionary checks of passwords will be performed.
host_based_services
(Whitespace- or comma-separated list.) Lists services which will get host-based
referral processing even if the server principal is not marked as host-based by the
client.
iprop_enable
(Boolean value.) Specifies whether incremental database propagation is enabled.
The default value is false.
iprop_master_ulogsize
(Integer.) Specifies the maximum number of log entries to be retained for
incremental propagation. The maximum value is 2500; the default value is 1000.
iprop_slave_poll
(Delta time string.) Specifies how often the slave KDC polls for new updates from
the master. The default value is 2m (that is, two minutes).
iprop_port
(Port number.) Specifies the port number to be used for incremental propagation.
This is required in both master and slave configuration files.
iprop_resync_timeout
(Delta time string.) Specifies the amount of time to wait for a full propagation
to complete. This is optional in configuration files, and is used by slave KDCs
only. The default value is 5 minutes (5m). New in release 1.11.
iprop_logfile
(File name.) Specifies where the update log file for the realm database is to be
stored. The default is to use the database_name entry from the realms section of
the krb5 config file, with .ulog appended. (NOTE: If database_name isn't specified
in the realms section, perhaps because the LDAP database back end is being used, or
the file name is specified in the [dbmodules] section, then the hard-coded default
for database_name is used. Determination of the iprop_logfile default value will
not use values from the [dbmodules] section.)
kadmind_port
(Port number.) Specifies the port on which the kadmind(8) daemon is to listen for
this realm. The assigned port for kadmind is 749, which is used by default.
key_stash_file
(String.) Specifies the location where the master key has been stored (via
kdb5_util stash). The default is /etc/krb5kdc/.k5.REALM, where REALM is the
Kerberos realm.
kdc_ports
(Whitespace- or comma-separated list.) Lists the ports on which the Kerberos
server should listen for UDP requests, as a comma-separated list of integers. The
default value is 88,750, which are the assigned Kerberos port and the port
historically used by Kerberos V4.
kdc_tcp_ports
(Whitespace- or comma-separated list.) Lists the ports on which the Kerberos
server should listen for TCP connections, as a comma-separated list of integers.
If this relation is not specified, the compiled-in default is not to listen for TCP
connections at all.
If you wish to change this (note that the current implementation has little
protection against denial-of-service attacks), the standard port number assigned
for Kerberos TCP traffic is port 88.
master_key_name
(String.) Specifies the name of the principal associated with the master key. The
default is K/M.
master_key_type
(Key type string.) Specifies the master key's key type. The default value for
this is aes256-cts-hmac-sha1-96. For a list of all possible values, see Encryption
types.
max_life
(duration string.) Specifies the maximum time period for which a ticket may be
valid in this realm. The default value is 24 hours.
max_renewable_life
(duration string.) Specifies the maximum time period during which a valid ticket
may be renewed in this realm. The default value is 0.
no_host_referral
(Whitespace- or comma-separated list.) Lists services to block from getting
host-based referral processing, even if the client marks the server principal as
host-based or the service is also listed in host_based_services. no_host_referral
= * will disable referral processing altogether.
des_crc_session_supported
(Boolean value). If set to true, the KDC will assume that service principals
support des-cbc-crc for session key enctype negotiation purposes. If
allow_weak_crypto in libdefaults is false, or if des-cbc-crc is not a permitted
enctype, then this variable has no effect. Defaults to true. New in release 1.11.
reject_bad_transit
(Boolean value.) If set to true, the KDC will check the list of transited realms
for cross-realm tickets against the transit path computed from the realm names and
the capaths section of its krb5.conf(5) file; if the path in the ticket to be
issued contains any realms not in the computed path, the ticket will not be issued,
and an error will be returned to the client instead. If this value is set to
false, such tickets will be issued anyways, and it will be left up to the
application server to validate the realm transit path.
If the disable-transited-check flag is set in the incoming request, this check is
not performed at all. Having the reject_bad_transit option will cause such ticket
requests to be rejected always.
This transit path checking and config file option currently apply only to TGS
requests.
The default value is true.
restrict_anonymous_to_tgt
(Boolean value.) If set to true, the KDC will reject ticket requests from
anonymous principals to service principals other than the realm's ticket-granting
service. This option allows anonymous PKINIT to be enabled for use as FAST armor
tickets without allowing anonymous authentication to services. The default value
is false. New in release 1.9.
supported_enctypes
(List of key:salt strings.) Specifies the default key/salt combinations of
principals for this realm. Any principals created through kadmin(1) will have keys
of these types. The default value for this tag is aes256-cts-hmac-sha1-96:normal
aes128-cts-hmac-sha1-96:normal des3-cbc-sha1:normal arcfour-hmac-md5:normal. For
lists of possible values, see Keysalt lists.
[dbdefaults]
The [dbdefaults] section specifies default values for some database parameters, to be used
if the [dbmodules] subsection does not contain a relation for the tag. See the
[dbmodules] section for the definitions of these relations.
• ldap_kerberos_container_dn
• ldap_kdc_dn
• ldap_kadmind_dn
• ldap_service_password_file
• ldap_servers
• ldap_conns_per_server
[dbmodules]
The [dbmodules] section contains parameters used by the KDC database library and database
modules. Each tag in the [dbmodules] section is the name of a Kerberos realm or a section
name specified by a realm's database_module parameter. The following example shows how to
define one database parameter for the ATHENA.MIT.EDU realm:
[dbmodules]
ATHENA.MIT.EDU = {
disable_last_success = true
}
The following tags may be specified in a [dbmodules] subsection:
database_name
This DB2-specific tag indicates the location of the database in the filesystem.
The default is /etc/krb5kdc/principal.
db_library
This tag indicates the name of the loadable database module. The value should be
db2 for the DB2 module and kldap for the LDAP module.
disable_last_success
If set to true, suppresses KDC updates to the "Last successful authentication"
field of principal entries requiring preauthentication. Setting this flag may
improve performance. (Principal entries which do not require preauthentication
never update the "Last successful authentication" field.). First introduced in
release 1.9.
disable_lockout
If set to true, suppresses KDC updates to the "Last failed authentication" and
"Failed password attempts" fields of principal entries requiring preauthentication.
Setting this flag may improve performance, but also disables account lockout.
First introduced in release 1.9.
ldap_conns_per_server
This LDAP-specific tag indicates the number of connections to be maintained per
LDAP server.
ldap_kadmind_dn
This LDAP-specific tag indicates the default bind DN for the kadmind(8) daemon.
kadmind does a login to the directory as this object. This object should have the
rights to read and write the Kerberos data in the LDAP database.
ldap_kdc_dn
This LDAP-specific tag indicates the default bind DN for the krb5kdc(8) daemon.
The KDC does a login to the directory as this object. This object should have the
rights to read the Kerberos data in the LDAP database, and to write data unless
disable_lockout and disable_last_success are true.
ldap_kerberos_container_dn
This LDAP-specific tag indicates the DN of the container object where the realm
objects will be located.
ldap_servers
This LDAP-specific tag indicates the list of LDAP servers that the Kerberos servers
can connect to. The list of LDAP servers is whitespace-separated. The LDAP server
is specified by a LDAP URI. It is recommended to use ldapi: or ldaps: URLs to
connect to the LDAP server.
ldap_service_password_file
This LDAP-specific tag indicates the file containing the stashed passwords (created
by kdb5_ldap_util stashsrvpw) for the ldap_kadmind_dn and ldap_kdc_dn objects.
This file must be kept secure.
The following tag may be specified directly in the [dbmodules] section to control where
database modules are loaded from:
db_module_dir
This tag controls where the plugin system looks for database modules. The value
should be an absolute path.
[logging]
The [logging] section indicates how krb5kdc(8) and kadmind(8) perform logging. The keys
in this section are daemon names, which may be one of:
admin_server
Specifies how kadmind(8) performs logging.
kdc Specifies how krb5kdc(8) performs logging.
default
Specifies how either daemon performs logging in the absence of relations specific
to the daemon.
Values are of the following forms:
FILE=filename or FILE:filename
This value causes the daemon's logging messages to go to the filename. If the =
form is used, the file is overwritten. If the : form is used, the file is appended
to.
STDERR This value causes the daemon's logging messages to go to its standard error stream.
CONSOLE
This value causes the daemon's logging messages to go to the console, if the system
supports it.
DEVICE=<devicename>
This causes the daemon's logging messages to go to the specified device.
SYSLOG[:severity[:facility]]
This causes the daemon's logging messages to go to the system log.
The severity argument specifies the default severity of system log messages. This
may be any of the following severities supported by the syslog(3) call, minus the
LOG_ prefix: EMERG, ALERT, CRIT, ERR, WARNING, NOTICE, INFO, and DEBUG.
The facility argument specifies the facility under which the messages are logged.
This may be any of the following facilities supported by the syslog(3) call minus
the LOG_ prefix: KERN, USER, MAIL, DAEMON, AUTH, LPR, NEWS, UUCP, CRON, and LOCAL0
through LOCAL7.
If no severity is specified, the default is ERR. If no facility is specified, the
default is AUTH.
In the following example, the logging messages from the KDC will go to the console and to
the system log under the facility LOG_DAEMON with default severity of LOG_INFO; and the
logging messages from the administrative server will be appended to the file
/var/adm/kadmin.log and sent to the device /dev/tty04.
[logging]
kdc = CONSOLE
kdc = SYSLOG:INFO:DAEMON
admin_server = FILE:/var/adm/kadmin.log
admin_server = DEVICE=/dev/tty04
[otp]
Each subsection of [otp] is the name of an OTP token type. The tags within the subsection
define the configuration required to forward a One Time Password request to a RADIUS
server.
For each token type, the following tags may be specified:
server This is the server to send the RADIUS request to. It can be a hostname with
optional port, an ip address with optional port, or a Unix domain socket address.
The default is /etc/krb5kdc/<name>.socket.
secret This tag indicates a filename (which may be relative to /etc/krb5kdc) containing
the secret used to encrypt the RADIUS packets. The secret should appear in the
first line of the file by itself; leading and trailing whitespace on the line will
be removed. If the value of server is a Unix domain socket address, this tag is
optional, and an empty secret will be used if it is not specified. Otherwise, this
tag is required.
timeout
An integer which specifies the time in seconds during which the KDC should attempt
to contact the RADIUS server. This tag is the total time across all retries and
should be less than the time which an OTP value remains valid for. The default is
5 seconds.
retries
This tag specifies the number of retries to make to the RADIUS server. The default
is 3 retries (4 tries).
strip_realm
If this tag is true, the principal without the realm will be passed to the RADIUS
server. Otherwise, the realm will be included. The default value is true.
In the following example, requests are sent to a remote server via UDP.
[otp]
MyRemoteTokenType = {
server = radius.mydomain.com:1812
secret = SEmfiajf42$
timeout = 15
retries = 5
strip_realm = true
}
An implicit default token type named DEFAULT is defined for when the per-principal
configuration does not specify a token type. Its configuration is shown below. You may
override this token type to something applicable for your situation.
[otp]
DEFAULT = {
strip_realm = false
}
PKINIT OPTIONS
Note The following are pkinit-specific options. These values may be specified in
[kdcdefaults] as global defaults, or within a realm-specific subsection of
[realms]. Also note that a realm-specific value over-rides, does not add to, a
generic [kdcdefaults] specification. The search order is:
1. realm-specific subsection of [realms],
[realms]
EXAMPLE.COM = {
pkinit_anchors = FILE:/usr/local/example.com.crt
}
2. generic value in the [kdcdefaults] section.
[kdcdefaults]
pkinit_anchors = DIR:/usr/local/generic_trusted_cas/
For information about the syntax of some of these options, see Specifying PKINIT identity
information in krb5.conf(5).
pkinit_anchors
Specifies the location of trusted anchor (root) certificates which the KDC trusts
to sign client certificates. This option is required if pkinit is to be supported
by the KDC. This option may be specified multiple times.
pkinit_dh_min_bits
Specifies the minimum number of bits the KDC is willing to accept for a client's
Diffie-Hellman key. The default is 2048.
pkinit_allow_upn
Specifies that the KDC is willing to accept client certificates with the Microsoft
UserPrincipalName (UPN) Subject Alternative Name (SAN). This means the KDC accepts
the binding of the UPN in the certificate to the Kerberos principal name. The
default value is false.
Without this option, the KDC will only accept certificates with the id-pkinit-san
as defined in RFC 4556. There is currently no option to disable SAN checking in
the KDC.
pkinit_eku_checking
This option specifies what Extended Key Usage (EKU) values the KDC is willing to
accept in client certificates. The values recognized in the kdc.conf file are:
kpClientAuth
This is the default value and specifies that client certificates must have
the id-pkinit-KPClientAuth EKU as defined in RFC 4556.
scLogin
If scLogin is specified, client certificates with the Microsoft Smart Card
Login EKU (id-ms-kp-sc-logon) will be accepted.
none If none is specified, then client certificates will not be checked to verify
they have an acceptable EKU. The use of this option is not recommended.
pkinit_identity
Specifies the location of the KDC's X.509 identity information. This option is
required if pkinit is to be supported by the KDC.
pkinit_kdc_ocsp
Specifies the location of the KDC's OCSP.
pkinit_mapping_file
Specifies the name of the ACL pkinit mapping file. This file maps principals to
the certificates that they can use.
pkinit_pool
Specifies the location of intermediate certificates which may be used by the KDC to
complete the trust chain between a client's certificate and a trusted anchor. This
option may be specified multiple times.
pkinit_revoke
Specifies the location of Certificate Revocation List (CRL) information to be used
by the KDC when verifying the validity of client certificates. This option may be
specified multiple times.
pkinit_require_crl_checking
The default certificate verification process will always check the available
revocation information to see if a certificate has been revoked. If a match is
found for the certificate in a CRL, verification fails. If the certificate being
verified is not listed in a CRL, or there is no CRL present for its issuing CA, and
pkinit_require_crl_checking is false, then verification succeeds.
However, if pkinit_require_crl_checking is true and there is no CRL information
available for the issuing CA, then verification fails.
pkinit_require_crl_checking should be set to true if the policy is such that
up-to-date CRLs must be present for every CA.
ENCRYPTION TYPES
Any tag in the configuration files which requires a list of encryption types can be set to
some combination of the following strings. Encryption types marked as "weak" are
available for compatibility but not recommended for use.

└─────────────────────────────────┴──────────────────────────────────┘
The string DEFAULT can be used to refer to the default set of types for the variable in
question. Types or families can be removed from the current list by prefixing them with a
minus sign ("-"). Types or families can be prefixed with a plus sign ("+") for symmetry;
it has the same meaning as just listing the type or family. For example, "DEFAULT -des"
would be the default set of encryption types with DES types removed, and "des3 DEFAULT"
would be the default set of encryption types with triple DES types moved to the front.
While aes128-cts and aes256-cts are supported for all Kerberos operations, they are not
supported by very old versions of our GSSAPI implementation (krb5-1.3.1 and earlier).
Services running versions of krb5 without AES support must not be given AES keys in the
KDC database.
KEYSALT LISTS
Kerberos keys for users are usually derived from passwords. Kerberos commands and
configuration parameters that affect generation of keys take lists of enctype-salttype
("keysalt") pairs, known as keysalt lists. Each keysalt pair is an enctype name followed
by a salttype name, in the format enc:salt. Individual keysalt list members are separated
by comma (",") characters or space characters. For example:
kadmin -e aes256-cts:normal,aes128-cts:normal
would start up kadmin so that by default it would generate password-derived keys for the
aes256-cts and aes128-cts encryption types, using a normal salt.
To ensure that people who happen to pick the same password do not have the same key,
Kerberos 5 incorporates more information into the key using something called a salt. The
supported salt types are as follows:
┌──────────┬──────────────────────────────────┐
│normal │ default for Kerberos Version 5 │
├──────────┼──────────────────────────────────┤
│v4 │ the only type used by Kerberos │
